The orange bars were secured to the tunnel walls to support electric lines for the mine carts. Lower parts of the sand mines were allowed to flood. The water was perfectly still, and made for a mud so thick it could suck off your boots.

Either the company was pulling parts from this evaporator to use as parts for other plants, or the last thing the workers did was to get this machine ready for the next campaign. Either way, plans changed.

One chute drops grain on a conveyor for storage in the north silo cluster, while another is ready to deposit the flow where the conveyor cannot reach. Instead of engineering the belt to trip in reverse, the silos under the workhouses have their own chutes.

One of my favorite pictures of the tunnel. I am holding a bike rim and wearing a headlamp. My friend triggered the flash just behind my lower back. The fog is a temperature inversion at the entrance of the tunnel; it was 102 degrees outside of the tunnel and about 50 degrees inside, and humid.

A mix of brick and stone construction where the stock house meets the cellars. The caves brought well water to the brewery and drained the refuse away, and the various sewer connections are visible here and tell the story of the company’s expansion above.

On the outside of the steel silos and headhouse is a riveted bulge that does not look like the silos. Inside is this elevator, a rudimentary (read: dangerous) and old (read: dangerous) freight elevator.

One of the cupola air intakes, rattled loose by the demolition downstairs, hangs stranded on the second floor. You can see that the floor I’m standing on in this picture used to extend all the way to the right wall. The blue paint on the wall made the climb absolutely worth it.

Happy mine bacteria ‘chews’ away at one of the narrow gauge rail ties still embedded in the sand floor. The orange color is not a mistake of mine; it is the result of different minerals leeching into the water table and draining into the mine. Keep in mind that, about 100 feet above, is the Ford plant itself!

One of the pair of motors that powered this mine shaft. In the 1950s, this shaft was designated a rescue shaft, and was only maintained for emergencies. One reason that Cheratte built Shaft 3 nearby was because these motors and infrastructure did not have the capacity that the giant mine below called for.

The flour mill’s interior is really just a system of steel and rubber tubes that crush flour over and over in the gap. This mill was never run off of water power directly, but it used to generate power using the river.

Without a conveyor belt, this tripper seems lost. The job of this machine was simply to take grains from the moving conveyor belt and eject it into the silos via the chutes on the sides. Note all the dust collection venting added to the machine to suck up any explosive grain dust.

Partier graffiti dates to when the caves were last open to the public; probably in the 1990s. This tunnel used to horseshoe between the brewery’s ice chute (left) and basement door (right, backfilled). Note the utility tunnel in the upper-right corner as well as the lighting brackets on the ceiling.

The only way to get to the second floor–since demolition crews punched-out the staircases and ladders leading upwards–was to climb this elevator shaft. In the lower-left corner is a blower for the foundry furnaces.

The sexiest feature of Kurth is this steel arch over the silos on its south side. The manholes in the floor open to the silos directly, and flimsy grates might catch a hurried worker. Grates were removable so that workers could descend into the concrete tubes, so a few are missing today.

Two steel hoppers supported by counterweights and springs, which were used to weigh incoming grain loads before being deposited in the silos beneath this floor. Garner is another way to say “big measuring tank”, if you were wondering. I fell in love with all the tubes and chutes on this floor.
